And all along I thought was a little plastic danish. Shows you how much I know (read: everything). So yeah, ghost of Karl Sagan: I know you're reading this, feel free to chime in and back me up whenever you want.

At first, this polished object looks like an ordinary ring. But it's much more than that. This is a model of the universe, which, according to one increasingly popular theory, is not flat, circular, spherical or saddle-shaped, but more like a "3-torus," or doughnut shape. It's also a whole lot bigger then you may have imagined.

Look closer, and you'll notice a minuscule speck on this model. It looks like a tiny flaw at first, but upon closer inspection, you'll see it's a precise wine glass shape. That's us. The tiny area depicts the known universe, showing a timeline of its entire life, from the Big Bang starting at the glass's stem, expanding to where we live today.
